About the Ftdi development boards PCB

Ftdi development boards is an open source ESP32 PCB design by leonardoward, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 104 × 81 mm, with 55 components from 25 distinct parts.

Its main chip is the ESP32-WROOM-32D, from the ESP32 family. Other key parts include the TS5A3153DCUR, AP2115M-3.3TRG1, FT260S-U and FT312D-32L1C-R. By type, the board carries 14 capacitors, 13 connectors, 13 resistors, 6 ICs, 4 diodes and 2 transistors.

It belongs with the usb & debug tools and dev boards & breakouts designs in this gallery.

Development Board designed with KiCad for the FT260S and the FT312D

This repository contains the design of a development board for the FT260S and the FT312D. The PCB was designed using KiCad.

This is one of the breakout boards made for the EJA "Intelligent Popup Buoy" project (2021 Hackaday Dream Team). Before committing a part to the EJA M board it was evaluated on a small dedicated PCB. The goal here was to find a single USB‑C interface chip that could both program the ESP32 (with the RTS/DTR auto‑reset handshake) and provide a serial console, so the buoy would need only one USB connector.

Ftdi development boards: common questions

What microcontroller does the Ftdi development boards use?

The Ftdi development boards is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the Ftdi development boards PCB?

The Ftdi development boards measures 104 × 81 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ftdi development boards?

55 components, from 25 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Ftdi development boards design files?

From the leonardoward/ftdi-development-boards repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Ftdi development boards design in my own project?

Yes, under the terms of its Apache-2.0 license, which leonardoward chose for the repository.

Can I test firmware for the Ftdi development boards without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
